List of advantages of longitudinal studies 1 they can show clear variable patterns over time one key advantage of performing longitudinal studies is their ability to show patterns of a variable over time, which is a very powerful way through which researchers come to learn about the relationships of cause and effect. 5 cross-sectional and longitudinal studies summary this chapter describes the design of cross-sectional studies in which observations at a single time point are made on all subjects.
